From the collection Dr. David P. Chandler on the site http://papaintellivision.com/
The documents herein regard the Mattel Electronics Intellivision project ranging from its inception in 1977 until the end of Chandler's involvement with the company in 1983.
This document with a copyright date of 1979 (though likely issued in 1980) contains the Intellivision Keyboard Component Owner’s Book. This would have shipped with most if not all of the 4,500 Keyboard Component peripherals sold and provides a full, user-focused guide on using the system without a great deal of technical information.
